They are usually around, only disappear if you get too close (which you try not to), and are always interesting.
The one above was taken at mid day, in the heat. Everything is hunkered at that time. This one was hiding from the heat along the marsh bank. I knelt down and caught him watching.
The first one above did his best to ignore me. The last one, end of day, moved past giving me absolutely no thought. I was not worth his time LOL.
